(I work in a retail store where a survey prints out after every receipt and often customers confuse this for the actual receipt when doing returns. My store also has a huge shoplifting problem so we have a strict policy on returns. No receipt means you can either do an exchange, or wait for a gift certificate to be mailed to you)

Me: “Oh… I’m sorry, sir, this is actually for a survey and not the real receipt.”

Him: “Well, that’s all I got!”

Me: “Oh, well, did you happen to use a card for this purchase? We can look it up that way, too.”

Him: “It was a gift! I don’t know how they bought it!”

Me: “Well, unfortunately, in that case I can only give you what the current selling price of it is, and you can either exchange it for something of the same value, or I can have store credit mailed to you.”

Him: “Well, how much is it?”

Me: “Let me check… looks like $7.99”

Him: “Just give me the store credit and I’ll go buy something today.”

Me: “Well, if you want to switch it out for something else, then go hang on to this, and when you make up your mind bring your items back up, and I can swap it out for you.”

Him: “I’m not going to take it with me! Why can’t you just give me store credit?!”

Me: “I can, it’s just going to have to be mailed to you. If you want to buy something today, you’ll have to find the items you want first.”
